5 Qlaims.

My invention relates to improvements in a machine for making neckties.

One of the objects of my invention is to provide a machine whereby the lining of a necktie can be sewed to its outer material.

Another object of the invention is to provide reliable and simple guide means for feeding the lining and the outer material of the necktie to guide means which will beshifted automatically in accordance with the tapered shape of the necktie.

' Other objects of the invention will be stated in the following description and drawings which illustrate preferred embodiments thereof, it being understood that the above statement of the objects of the invention is intended generally to explain the same without limiting it in any manner.

Fig. l is a top plan view of the improved device.

Fig. 2 is an end elevation of Fig. 1.

Fig. 3 is a sectional view, partially in elevation. on the line 3-4 of Fig. 1.

Fig. 4 is a development in plan view of the control cam which is shownin Figs. 1 and 2.

Fig. 5 is a top plan view showing another embodiment of the invention.

Fig. 6 is an end elevation of Fig. 5.

Fig. 7 is a sectional view on the line 1-1 of Fig. 5- 1 The machine comprises a drive shaft I. which is driven by any suitable gear or by any other means. This drive shaft I passes through a wallof'the U -shaped table or frame 4 of the machine.

A cam 2, having a huh I. ismounted upon the a shaft I, so that said cam 2 and the shaft I turn in unison. Spacing bushings 8 are provided between the hub I and the bearings 3. A guard 9,

. which is connected to the top plate of the frame 4, is located below the bottom of the cam I so as to prevent the lining L and the tape 8 from contacting with said cam.

A guide II is also connected tothe underside An ordinary bearing member 5 is pro-- vided in said wall. The frame is connected to.

of the top wall of the frame This guide to has a channel-shaped portion I i, which serves as a guide to feed the strip of tape S.

The top wall of the frame is provided with a slot l2, which extends inwardly from one of the longitudinal edges of said top wall. Guide levers l4 and ii are pivotally connected to thetop wall of the frame 4, by means of pins Ma and lid. These guide levers l5 have the angular shape shown in Fig. 3. Each of said guide levers has a straight leg which is located close to the underside of the top wall of. the frame. Each of said guide levers also has an inwardly bent portion B which contacts with the respective edge of the owl.

As shown in Fig. 3, the tapered lining L, together with the tape S, are fed upwardly through the slot I2. The spacing ends or outer ends of the guide rods l4 and I5 are automatically spaced so that the distance between the outer ends of said rods I4 and I5 is substantially equal at all times to the width of the tapered lining strip L.

The channel-guide I I also enables the operator to guide the movement of the strip S so that its longitudinal axis at all times coincides with the longitudinal axis of thejtapered lining L.

Tension springs l8 hold the bent end B of the guide rods l4 and I5 against the edges of the ram 2. Said cam is shaped so that the distance between the outer ends of the guide rods II and i5 is at all timesv equal to the respective width of the lining L.

As shown in the development of the cam in Fig. 4,-said cam has a substantially uniform tapered shape between the lines which are identifled by reference numerals l9 and 20. The cam has a portion between the lines identified by reference numerals 20 and 2|, which is of uniform width, as indicated in Fig. 2. The remaining portion of the cam, between the lines identifled by reference numerals 2| and 22, is tapered, its taper being opposite to that portion of the cam which is between the reference numerals 19 and 20.

The shape of the lining L of the" necktie is indicated in broken lines in'Fig. 4. It can be seen that the taper of the tapered portions of the cam is opposite to the taper of the corresponding portions of .the lining.

The lining L has two oppositely tapered end portions and an intermediate portion of uniform width. It willbe noted that the distance between the outer ends of the guide rods I! and I5 is greatest, whenv the inner ends of said guide 58 rods contact" with the narrow portion of the wall of the frame 4.

cam. The relative opposite tapers of the cam and of the lining causes the proper guid ng of the lining strip L.

In the embodiment shown in Figs. -7, the frame 4 is substantially the same as in the first embodiment. A drive shaft la is provided with internally threaded portions 24 and 25, which are oppositely threaded, and with an intermediate integral portion 29. The drive shaft la is turnably connected by means of a pivot screw 26 to one of the vertical walls of the frame 4.

A bearing washer 21 is provided between the head of the screw 26 and the adjacent vertical Collars 30 are slidably mounted upon the member 29, and compression springs 3| keep the collars 30 at the outer ends of the members 29. v

A collar 32 is located intermediate the springs 3|. Said collar 32 is connectedto the member 29 by means of a fastening member 33. Guides 28 and 28a having tapped bores, are mounted upon the members 24 and 25. These guides have planar faces which abut the adjacent planar surface'of the top wall of the frame 4.

Therefore when' the shaft la is turned, the guide members 28 and 28a are moved transversely towards each other or away from each other, depending upon the direction of revolution of the shaft la.

The speed of turning of the shaft la is regulated by any suitable manual or automatic means, so that the distance between the guides 28 and 28a is at all times equal to the width of the lining strip L.

The guides 28 and 28a are prevented from moving off the threaded members. 24 and 25, by means of the collars 38. The guides 28 and 28a are made suificiently wide so that they are held upon the threaded members 24 and 25 when said guides 28 and 28a abut the collars 30.

The device herein is an improvement upon the device originally described in application Ser. No. 143,708 filed in the United States Patent Office on May 20, 1937, and later covered by the continuation-in-part application, Serial No. 343,515, filed July 2, 1940, to take the place of the originallyfiled application, to which reference can be made for further details.

The folded outer material T of the necktie is led over the top wall of the member 4, the sewing operation being similar to that" shown in Fig. 7 of the aforesaid application Ser. No. 343,515. a

As the lining L passes through the slot l2 from the underside of the top wall of the frame, to the top surface of said top wall, the forward feeding movement of the lining strip is guided accurately by the guiding ends of the rods l4 and I5. If the operator feeds the strip S forwardly so that it is maintained straight, the channel member I l maintains the strip S in proper position relative to the lining L.

For convenience in describing the invention in the claims, it is assumed that the plane of the top wall of the frame 4 is horizontal. However, this is immaterial for the purposes of the invention.

The shaft I can actuate suitable feed-mechanism such as feed rolls or the like, for feeding lining L, strip S, and material T automatically to the stitch-forming mechanism.

The invention above described may be varied in construction within the scope of the claims, for the particular device selected to illustrate the invention is but one of many concrete embodiments of the same. The invention therefore is not to be restricted to the precise details of the structure shown and described.
